The Answer is obviously 6
a(n) = a+(n-1)d
here, a = 95, d= 90-95 = -5
a(n) = 95+(n-1)-5
a(n) = 95+5-5n
a(n) = 100-5n ......it's your answer
To find the answer you need to add the volumes of all of the cubes. The volume of a cube = L^3 where L is the length of an edge. Since each cube has edges of L = 1/2 inch, L^3 = (1/2)^3 inch^3 = 1/8 inch^3.
Since there are 1120 cubes in the prism, the total volume of the prism is:
V = 1120 * 1/8 inch^3 = 140 inch^3.
Answer:
The equation of line having slope m and y-intercept b is
y = m x + b
The other two equations of line in the same family having intercepts p and q are,keeping the slope same i.e m , described in the question are
→ y= m x + p
→ y = m x + q
As both the equation have same slope i.e m , so lines will be parallel, but their Y - intercept are different i.e distance from the origin where it cuts the y-axis are different i.e at a distance of p and q from origin.
